Ice cores showed the age of a military plane buried in the artic as thousands of years old.
Similarly, dendrochronology measures the tree rings in trees and assumes they represent years.
ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.
This technique does not give specific ages to items.
He would have answered that the Earth was ancient, that there had not been a Noachian flood, and that the species of life had not been fixed over the history of Earth.
In short, Genesis was an allegory and not literal history.
Wiens has a Ph D in Physics, with a minor in Geology.
The rocks formed during a period belong to a stratigraphic unit called a system.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.The story of this great change in the conception of the history of Earth is not a simple one.The chronicle of this great change can be broken into five periods; ran from AD 1600-1700.
Ice core sampling normally uses the assumption that the ring bands observed represents years.
